龍門外防護(hù)采用四開門設(shè)計(jì)（龍門加工中心三開門設(shè)計(jì)），兩側(cè)為推拉門，前后為貫通式對開門，極大方面客戶上下工件。

龍門橫梁有樓梯式檢修平臺，極大方便對Z、Y軸的檢測維修與保養(yǎng)。

龍門X軸采用支撐式滑輪組內(nèi)防護(hù)。有效的支撐了防護(hù)的重量，使防護(hù)在運(yùn)動時(shí)，始終保持與導(dǎo)軌的平行，不易產(chǎn)生變形防水可靠性得到提高，壽命得到了提高。Y軸采用了全封閉耐腐蝕的風(fēng)琴式防護(hù)，具有防護(hù)效果好封閉效果好等特點(diǎn)。

The external safety enclosure of the gantry adopts a four-door design (compared to the three-door design of gantry machining centers); the two sides feature sliding doors, while the front and rear are through double-opening doors, greatly facilitating the loading and unloading of workpieces for customers. 

The gantry beam is equipped with a stair-like maintenance platform, greatly convenient for inspecting, repairing, and maintaining the Z and Y axes. 

The X-axis of the gantry uses a support-type pulley group with internal protection. This effectively supports the weight of the protective guard, ensuring it remains parallel to the guide rail during movement, reducing deformation and enhancing waterproof and reliability, thus increasing the lifespan. The Y-axis features a fully enclosed, corrosion-resistant bellows-type protective cover, which offers excellent protection and sealing performance.
